Aiuto....

#include "cv.h" 
#include "highgui.h" 
#include "cxcore.h" 
#include <iostream> 

using namespace std; 
 
int main() 
{ 
	string imageFile = "C:\\fruit.JPG";   
    IplImage* src = cvLoadImage(imageFile.c_str()); 
    int width = src->width; 
    int height = src->height; 
    IplImage* result = cvCreateImage(cvSize(width,height),8,3);  
    cvPyrMeanShiftFiltering(src,result,20,40,1);   
 
    cvReleaseImage(&src); 
    cvReleaseImage(&result); 
    return 0; 
}
non riesco a capire perchè non mi genera le finestre con le immagini...
